Abstract

A gas bubble brick for metallurgical vessels consists of a porous, gas-permeable shaped brick (2) made of refractory material, a gas-tight partial encasing surrounding the latter, which encasing is welded together from a metal jacket (4) extending around the lateral circumferential area of the shaped brick and a metal cover (6) covering the outer face of the shaped brick, a gas supply pipe (10) which is welded to the rim of a central gas inlet orifice (8) of the metal cover (6), as well as a break-through safeguard in the area of the gas supply pipe. In order to prevent closure of the gas bubble brick in the gas outlet area and in order thereby to ensure purge readiness, a constricted cross-section (12) is provided inside the gas supply pipe (10) at a distance from the gas inlet orifice (8) of the metal cover (6), there being provided in the pipe section between the metal cover and the constricted cross-section a closure body (17), which is movable at least in the axial direction of the gas supply pipe and is, for example, a copper ball or the like, the cross-section of which is smaller than the inside diameter of the gas supply pipe (10) and greater than the constricted cross-section (12). The closure body (17), together with the constricted cross-section (12), thereby forms a non-return valve, which prevents a pressure drop occurring in the gas bubble brick after switching off the gas supply.
